XSS Defense in Spring Boot Applications
The article explains how to protect Spring Boot applications from XSS attacks by using custom annotations such as @XSS with an XssValidator and by implementing a request‑filter chain—including XssFilter and XssWrapper—to sanitize input, demonstrating through tests that both approaches reliably secure user data.
本文探讨如何在Spring Boot应用程序中有效地防御XSS攻击。我们介绍了两种主要的防御手段：注解和过滤器。通过注解，开发者可以在方法或字段级别对输入进行校验，防止XSS攻击脚本注入。此外，过滤器提供了一种更通用的方法，通过拦截请求并清理输入内容，确保安全。
注解的详细实现包括自定义注解和注解处理器，例如 @XSS 注解和 XssValidator 类，用于检查输入是否包含恶意脚本。过滤器配置涉及依赖注入、配置类和自定义过滤器，如 XssFilter 和 XssWrapper ，用于拦截请求并清理XSS攻击。
测试结果显示，注解和过滤器均能有效防御XSS攻击，确保用户数据安全和应用稳定运行。
